To all ywhom it may concern Be it known that I, ROBERT C. HALL, a citizen of the United States, and a i'esideiit of Lexington, county of Fayette, and State of Kentucky, have made and invented certain new and useful Improvements yin Methods of Patching Hose and Tools Therefor, of which the following is a specification.

My invention relates to a new and useful improvement in hose patching tools, readily adaptable for use with either a cloth or rubber hose and especially designed for use in patching or vuleanizing steam, or water hose used in connection-.with freight or passenger cars.

It will be understood that the air or steam hose in use on railroad cars generally have a casting at their one end that is oftentimes difficult to remove, the casting usually having an opening therein which is smaller than the internal diameter of the hose to which it is fastened.

An object of my invention therefore is to provide a tool having at its lower end an expansible. member, the diameter of which when collapsed is smaller than that of the opening of the castings usually connected or attached to the hose, the said member however being capable of expanding to a di ameter as great or greater than the internal diameter of the hose in which the tool is to bev inserted.

-Another object of my invention is to provide a tool wherein the end member may be expanded for the purpose of placing a patch on the inner surface of the hose, and also capable of being contracted after the patch is set in place.

Still another object of my invention is to produce a -tool of the character described wherein the parts may be quickly and readilv assembled, cheap to manufacture, and neat in appearance.

lith these and other objects in view my invention consists in certain new and novel constructions and combinations of parts as will hereinafter he more fully described and pointed out in the claims.

1n the drawings Figure 1 is a longitudinal sectional view of the tool with the end niembe'r in its contracted or normal position. Fig. 2 is a similar view but with the end member in its expanded position. Fig. 3 is also a longitudinal sectional view but.

taken at right angles to Fig. 1. Fig. 4 is a sectional. view taken on line 1-4 of Fig. 3. Fig. 5 is a sectional view taken on line eof Fig. 3. Fig. 6 is a detail perspective view of the 'upper connecting means. Fig. 7 is a view of one of the shoes or plates of the expanding member. Fig. 8 is the inner member for operating the expandible member carrying the shoe 7.

Referring now to Fig. 1 it will beseen that there is provided an outer casing or member 1 externally threaded at its upper end 2 and on which is removably threaded a handle 3, this handle being provided with the openingl L1 and the internal threads just mentioned 5, and is provided also at its upper end with an opening 6 through which .passes an externally threaded pin 7, the pin extending for a short distance into the said handle 3. Alsecoiid handle S is provided for alining means which simply slides up and down on the outer casing or member 1.

Provided in the outer member 1 is a slot 9, and provided in the handle S is an opening for the reception of a pin 10, which also passes through a slot in an inner member to be afterward referred to.

Securedat the lower end of the member 1 is a. connecting member 11 which is shown in detail in Fig. 6, the upper portion being reduced and the lower portion thereof being bifurcated to form a channel portion longitudinally thereof as shown at 1'2. The upper portion of this connecting member 11 is provided with a hole or passageway 13 for the reception of a pin 1i which also" passes through at the opposite side of a surrounding or circular collar 15.

Referring now to Fig. S there is shown an inner casing or member 1G the external di- -ameter of which is less than the internal diameter of the member l. and is adapted t0 Iit. within the same and be movable therein.

lIt will. also be noticed that this inner member 1G must be longer than the outer casing and is also provided 'midway thereof with a slot 1T extending longitudinally thereof, :aid slot 1T being in alinenient with the slot in the outer casing and through which passes the pin 10 alreadyv mentioned. The lower end of this inner member 1G is bifureated to form the two arms 1S and between these armsflS and at the upper end thereof is lplaced, the connecting member 11.

io hold thesame tothe inner membei` 17 Thus' far it willbe seen that we have an -tol the Vconnectir'i'g member 11 the only distinction however being that the hole or passageway in the upper reduced portion ex- 'tends transversely thereof instead of longiy l tudinally. vThearms 1 8 are provided with a hole 19 for' the reception of a pin 20 which passes through the said arms and through the lower connecting member 18a to securely outer member to which is secured a con- `necting.member'11\, and also an inner member and-at the lower end of which is also lsecured -a similar connecting member, and

.the inner and louter member capable of movementwith relation toeach other.

v Referring now to Figs. 1 and 2 it will be seen that pivotally connected to the connecting member 11' are the links 21 which links" are shown as cruciform, and similarly,

vided with casing or mrub "member 16 and-- h tb the lower connecting member 18L are similar links 22. The other ends of these links 21 are connected to two shoesor plates 23 and 24 which are provided with lugs or' fastening means- 25 as shown in sectional view Fig. 7 which fastening means are prothe slots 26, these shoes or plates extending for the greater distance around vthe inner portion. of a hose when inserted.

V'It will thus-'Ibeseen that within the outer `A`1 is the inner casing or readed on the upper end ofthe outercasing 1 isthe handle 3 and up into. which extends the upper end of the inner member 16 and freely through the zupper portion of the 'handle extends the ',threaded pin whichA also engages correctly 40;'. v

' alining purposes lits around the outer meml in'i'i'ercasing 16. "The sliding. handle 8 for ber 1 andthe pin 10 passes through the slot inboth the innerandouter Amembers and prevents any relative rotation of the two members.

Secured to'the outer member is the conneetingIgmember 11 to which in turn are fastened the pivotal .links 21rwhieh in their turn are connected tothe shoes or plates 23 and 24, and to the other ends of the shoes or plates ,are the pivotal links which are connected to the connecting member 18 which is fastened by the pin 20 to the two arms of the inner member casing 17, the upper connecting member litting within the two arms 18.

The` operation of the device is therefore as follows: Starting with the plates or shoes in their normal or closed position they are inserted- 1n a hose to be patched, and laid on one ,bf the .shoes 23 or 24 is a piece of rubber or cloth 30, it depending of course be patched, the-patch being coated with cement or other adhesive means. After the plates have been links will operate to throw or force the shoes or plates 23 in their outward position, as clearly shown in Fig-2. The tool is then allowed to remain in this position until the patch has adhered to the casing a afterward the handle is turned in a right hand manner which in turn forces the inner member downwardly through the outer member and forces the connecting member 18a away from the connecting member 11, and through the action of the pivotal links already mentioned draws the plate or shoes inwardly, when the tool may then be removed.

The handle S is used for alinement purposes and to securely grip the tool and the pin passing through the slots in both the' inner and outer members prevent the inner member from turning which would change the position of the shoes or plates within the casing.

With the use of the above tool it will be seen that the same may be' inserted through a hole, thev internal diameter of which is much less than that of the hose to be patched; that a patch may be applied to the inner or internal diameter of the hose, and at the same time suiicient pressure may be exerted thereon to assist in the adhesion and the tool may then be operated. to again compress the plates so that the tool may be withdrawn. After the inner patch has been inserted, the outer surface of the hose may be filled into the desired thickness with layers of rubber or cloth or cloth and cement, it depending` on the nature of the article to be finished.

It will be understood that the tool may be as long as desired and that many minor changes may be made without affecting or without in any way interfering with the scope of the invention.

From the foregoing it will be seen that the tool is a cbmparatively simple one, con sisting of essentially an inner and an outer member, an upper 'handle and an alining` handle. connecting` members and two shoes two oppositely arranged concave plates connected thereto and capable of moving transversely to the axis of' said members when` one of said members is moved with Irelation to. the other.

3. In a repair tool an inner and outer member, means for providing against relative .rotation of said inner and outer members, oppositely arranged concave plates connected to said members and'capable Y of moving transversely to the axis or" said members when one of said members is moved` with relation to the other.

4. In `a repair toolv'an -inner and outer `member and opppsitely arranged plates connected thereto, means secured to said members to movex to thereby cause said plates to move transversely with respect to the aXis of said members yand remain parallel to each other throughout their movement.
